  4. 3. Measurement of the Reaction pp→ppπ+π-π0 with CELSIUS/WASA at 1.36 GeV

    Författare :Marek Jacewicz; Sven Kullander; Hans Ströher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : A versatile detector setup prepared by the CELSIUS/WASA collaboration for exclusive studies of rare processes produced in proton and deuteron collisions with hydrogen and deuterium pellet targets is presented. For the near-threshold production of light mesons, π0 and η, the scattered beam and target particles are measured in the forward detector, while the products of the decaying mesons are registered in a central detector covering close-to-4π sr.

    Sammanfattning : Neutral two- and three-pion productions in proton-proton collisions at a center of mass energy of 2.465 GeV have been studied using the WASA detector and an internal pellet target at the CELSIUS storage ring in Uppsala. LÄS MER

  7. 5. A phylogenetic analysis of rasborin fishes (Teleostei, Cyprinidae)

    Författare :Te-Yu Liao; Sven Kullander; Paul Skelton; Stockholms universitet; []
    Nyckelord :Rasbora; Chedrina; Danionina; Danionini; Rasborini; Danioninae; Opsariichthyinae; Cyprinidae; Cypriniformes; phylogeny; systematics; Africa; Asia; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : The Danioninae (sensu lato) were until recently considered to be a paraphyletic group, comprising about 200 species and distributed over Africa and southern and eastern Asia. There was no morphological diagnosis for the Danioninae, and also the composition of the subfamily, and the interrelationships of included genera have been contentious. LÄS MER
